Description
The TSH8x series offers single and dual operational amplifiers featuring high video performance with large bandwidth, low distortion and excellent supply voltage rejection. These amplifiers also feature large output voltage swing and high output current capability to drive standard 150 loads. Running at single or dual supply voltage from 4.5V to 12V, these amplifiers are tested at 5V (2.5V) and 10V (5V) supplies. The TSH81 also features a standby mode, which allows the operational amplifier to be put into a standby mode with low power consumption and high output impedance. This function allows power saving or signal switching/multiplexing for high-speed applications and video applications. For board space and weight saving, the TSH8x series is proposed in SOT23-5, TSSOP8 and SO-8 plastic micropackages.

Layout precautions
To use the TSH8X circuits in the best manner at high frequencies, some precautions have to be taken for power supplies:
In high-speed circuit applications, the implementation of a proper ground plane on both sides of the PCB is mandatory to ensure low inductance and low resistance common return. Power supply bypass capacitors (4.7F and ceramic 100pF) should be placed as close as possible to the IC pins in order to improve high frequency bypassing and reduce harmonic distortion. The power supply capacitors must be incorporated for both the negative and the positive pins. All inputs and outputs must be properly terminated with output resistors; thus, the amplifier load is resistive only and the stability of the amplifier will be improved. All leads must be wide and as short as possible especially for op-amp inputs and outputs in order to decrease parasitic capacitance and inductance.
In lower gain applications, use a low feedback resistance (under 1k) to reduce the time constant with parasitic capacitance. Choose component sizes as small as possible (SMD). On the output, the load capacitance must be negligible to maintain good stability. You can put a serial resistance as close as possible to the output pin to minimize the effect of the load capacitance.

Video capabilities
To characterize the differential phase and differential gain a CCIR330 video line is used. The video line contains 5 (flat) levels of luminance onto which the chrominance signal is superimposed. The luminance gives various amplitudes which define the saturation of the signal. The chrominance gives various phases which define the color of the signal. Differential phase (or differential gain) distortion is present if a signal chrominance phase (gain) is affected by luminance level. Differential phase and gain represent the ability to uniformly process the high frequency information at all luminance levels. When differential gain is present, color saturation is not correctly reproduced. The input generator is the Rhode & Schwarz CCVS. The output measurement is done by the Rhode and Schwarz VSA.

Precautions on asymmetrical supply operation
The TSH8x can be used either with a dual or a single supply. If a single supply is used, the inputs are biased to the mid-supply voltage (+VCC/2). This bias network must be carefully designed, in order to reject any noise present on the supply rail. As the bias current is 15A, you should use a high resistance R1 (approximately 10k) to avoid introducing an offset mismatch at the amplifier inputs. Figure 33. Asymmetrical supply schematic diagram

C1, C2, C3 are bypass capacitors intended to filter perturbation from VCC. The following capacitor values are appropriate: C1=100nF and C2=C3=100F R2 and R3 are such that the current through them must be superior to 100 times the bias current. Therefore, you could use the following resistance values: R2=R3=4.7k Cin and Cout are chosen to filter the DC signal by the low pass filters (R1, Cin) and (Rout, Cout). With R1=10k, Rout=RL=150, and Cin=2F, Cout=220F the cutoff frequency obtained is lower than 10Hz. Figure 34. Use of the TSH8x in gain = -1 configuration
